RE: [Xen-users] AMD-V or VT
Correction, for clarity:
VT and AMD-V give you hardware virtualization, I am not familiar with the
various caveats each may or may not entail.
VT-D is necessary for PCI passthrough in an Intel system, IOMMU is necessary
for PCI passthrough in an AMD system.
AMD may name IOMMU support something else when they officially start
supporting it, or it may be their official name, I don?t know.
Intel systems that don?t support VT can still be purchased, as well as Intel
systems that support VT, but not VT-D (both the motherboard and the
processor must support the given technology, this will probably be true of
AMD systems as well, but I don?t know).

VT currently because you get PCI Pass-through support. New DDR3 Opterons
will offer PCI Passthrough later this year but I assume you are buying now.

Sorry for simple question:
What techonology is better for HVM-using: VT or AMD-V. Thank's a lot if any
can take answer.
